There's a common pattern in science. We develop some new process or tool that allows us to gather all kinds of data we've never had before, the data threatens to overturn all we've assumed about some long-established theory, ...

Self-correcting quantum computers within reach?

Quantum computers promise to reach speeds and efficiencies impossible for even the fastest supercomputers of today. Yet the technology hasn't seen much scale-up and commercialization largely due to its inability to self-correct. ...

A new way to erase quantum computer errors

Quantum computers of the future hold promise in solving all sorts of problems. For example, they could lead to more sustainable materials and new medicines, and even crack the hardest problems in fundamental physics. But ...

Illuminating errors creates a new paradigm for quantum computing

Researchers have developed a method that can reveal the location of errors in quantum computers, making them up to 10 times easier to correct. This will significantly accelerate progress towards large-scale quantum computers ...
